Abstract

Generalized data of biogenic properties investigations of the Black Sea deep waters from its reduction zone for marine algae are presented. It is shown on board and in laboratory that after pre-oxidation of hydrogen sulphide by intensive aeration of the deep waters lifted to the surface of the sea, they are ready to be used for cultivation of the Black Sea unicellular, planktonic, and multicellular, benthic, algae instead of artificial medium. Naturally balanced micro- and macroelements structure and enriched content of nutrients are characterized the Black Sea deep waters. As a matter of fact after full oxidation of hydrogen sulphide they become the high-quality nutrient medium comparable with and even exceeding of the best man-made cultural medium.
